I spent an entire day last week attempting to build hadoop with LZO compression support. There are many outdated guides on the internet about how to do this, and I eventually gave up and spent a few hours getting the cloudera packages to install in a Dockerfile so I could reproduce my work later.
Figuring out which software packages I needed, how to modify my environment variables, which compiler to get, and where to put everything in the correct directory was the entire difficulty.
If it were written in Go instead of Java, I could have done `go get apache.org/hadoop` and it would have been done instead of giving up after hours of frustration.
Go has almost no new features that make it an interesting language from a programming language perspective. Go's win is that it makes the actual running of real software in production better. Hadoop's difficult is exactly why InfluxDB exists at all.

This complaint is just about packaging, and not the language itself. Any project can have good or back packing scripts, and for Java there are plenty of ways to make it "good".
Not to mention, the BUILDING.txt document clearly states they use maven[1] and to build you just do: mvn compile

This might just be a familiarity issue, because once you launch the program, all things are equal.
And yes, you can bundle a JVM with your java app, which makes it exactly like GO's statically linked runtime and just as portable without any fuss.
Than Java? At best, GO performs on par with Java, but is often measured 10-20% slower.[1][2][3]
This is usually attributed to the far more mature optimizing compiler in the JVM, which ultimately compiles bytecode down to native machine code, especially for hot paths. Java performance for long running applications is on par with C (one of the reasons it's a primary choice for very high performing applications such as HFT, Stock Exchanges, Banking, etc).

Java absolutely supports concurrency "out of the box"...[4]
